Volume Booster
Increase or decrease the volume of any audio file with precise gain control. 100% browser-based via ffmpeg.wasm.
How Volume Booster works
Any format — MP3, WAV, AAC, FLAC, OGG, M4A.
1.0× keeps volume unchanged. 2.0× is twice as loud. 0.5× is half. Use restraint — going too high causes clipping.
Encoded with LAME MP3 at 192 kbps.
Frequently asked
Will boosting distort the audio?+
Gains above 2.0× often clip peaks. If the original is well-recorded, 1.5–2.0× is a safe ceiling.
How much can I boost?+
Up to 5.0× via the slider — but past 3× you'll almost certainly hear clipping. Try 1.5× first.
Is my audio uploaded?+
Never. Everything runs in your browser via ffmpeg.wasm.
